The multi-sport event takes place outside the FIFA international window, so clubs are not obliged to release players, and Afghanistan and Syria withdrew before the Games even began.
That left only two teams in Group C, Hong Kong and Uzbekistan, and both of them advanced to the next round without making a single shot on goal.
Former Croatia defender Stimac, who played for Derby County and West Ham as a player, said it was a big problem.
Twenty-one of the 22 players on my (original) list are not here today, he said after the team lost 5-1 to China at the start of their campaign.
After a 1-0 win over Bangladesh, they have not given up hope of reaching the knockout round despite several players only arriving for the game just before kick-off.
This is the seventh roster I’ve changed and prepared to bring the team here, said Stimac, who was in the lineup xof the Orvat team that finished third at the 1998 World Cup.
I am well aware of how difficult it is because (Indian) clubs are not under pressure to let their players go.
But I am happy because I see that some teams withdrew at the last moment, (as) they couldn’t get enough players, like Afghanistan, like Syria, and that is a big problem for the whole tournament now.
Indian defender Sandesh Jhingan added: We haven’t practiced on the field (as a whole team) yet and we have already played two games.
Despite the disruption in preparation, Stimac urged his wards not to let up.
Once we get the full squad together, we will cause problems for anyone in Asia. Trust me, he said.
They will meet the Myanmar team on Sunday.
